3 Claims.

The present invention relates to window constructions and more particularly to a novel window unit having a double lift slidable sash that may be readily raised or lowered and when in closed position, makes for 'a weather and watertight seal, thus admirably adapting the window for marine use.

The novel window is of non-ferrous metals with the frame sections and the sash members formed of extruded sections and preferably mitered and welded together to provide a substantially rigid construction.

Another novel featur of the present invention resides in the manner of sealing the window.

when the slidable sash is in closed position,

thereby making'the structurewatertight. This is accomplished by a camming action between the slidable sash and the side jambs of the'window frame when this sash member is in closed position, resulting in a weathertight sealing contact between the sash members and frame. In the disclosed embodiment, this camming action is accomplished-by complementary cams or embossments on the side jambs of the window frame and the side rails of the slidable sash.

2 Further objects are to provide a construction of maximum simplicity, efliciency, economy and ease of assembly and operation, and such further objects, advantages and capabilities as will later more fully appear and areinherently possessed thereby.

The invention further resides in the construction, combination and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferred embodition taken in a plane represented by line 2-2.

Fig. 3 is a fragmentary enlarged view in horizontal cross section taken on the line ll of Fig. 1.

'Fig. 4 is a fragmentary enlarged view in elevation of the inside of the window, parts being broken away to more clearly show the catch or. latch mechanism. r f

Fig. 5 is a fragmentary view in-vertical cross section through the upp r sash rail.

, Fig. 6 is a fragmentary enlarged view in horizontal cross section through the window frame and side jambs, with the sliding sash shown in end elevation and in closed position.

Fig. 7 is a fragmentary view in horizontal cross section taken on the line 1-1 of Fig. 1.

Referring more particularly to the disclosure in the embodiment selected to illustrate the invention, the novel window construction I is shown as mounted in a ship in which the numeral 2 refers to the hull or metal plate of the ship structure, although it is tobe understood that the window is admiraly adapted for mounting in buildings or other structures where a weathertight seal is desired. The window I is provided with a metal frame 3 secured in an opening in,

the hull or metal plate of the ship by means of an external flange or metal trim 4. is preferably of extruded construction and welded at the comers so as to provide a rigid assembly. Any suitable securingmeans such as welding, bolts or the like may be employed for anchoring th frame in the opening in the hull.

Within the frame 3 are mounted sash members 5 and 6, the upper sashmember 5 being slidable within the frame, while the sash 8 is preferably retained stationary. As more clearly shown in Figs. 2 and 3, the upper sash is provided with a top rail I, side rails 8 and bottom. rail 9, each formed with an outwardly opening channel ll and an offset, inwardly or laterally opening groove ll adapted to receive a weather strip I! of felt laminae or the like to completely seal this sash against the adjoining frame sections when this sash is in closed position. To facilitate and augment the sealing effect, the exterior face of the side 'rails of the. upper sash are embossed adjacent their upper and lowerends to provide tapered cam surfaces i3 and It adapted to abut and ride over complementary tapered cam surfaces or embcssments i5 and IS on the inner faces of the opposite side jambs l I of the frame 3.

These side jambs are so formed as to provide opposed vertically extending channels or guideways I! between the exterior flange or trim l9 40 and a parting strip or channel member 20 secured in any suitable manner as by ,means of ma-, chine screws, bolts or the like 2| in the upper portion of a depressed recess or'groove 22 of the Similarly arranged exterior flange. or trim l9 and parting strip 20 are associated side lambs.

with the upper or head jamb 23. The side jambs l1, head Jamb 23 and sill 24 ar preferably ofextruded construction, although they may be of coldrolled sections, and preferably of identical contour, receiving not only the upper slidable sash but also a lower sash 8 mounted in a fixed or stationary position but adapted to be readily assembled and disassmbled, as required. The upper and lower sash members are also preferassembled and disassembled, as required. The ably of a somewhat similar constructionso as to permit a universal use or standardizationof the sash either as a sliding or fixed member.

In the disclosed embodiment of lower sash I,

the top rail 25, side rails 26 and bottom rail '21 This frame are of identical construction, each being provided or formed with spaced outwardly projecting flanges or legs 23 having inturnedproiections 23 adapted to be received within the inwardly opening channel and abutting against spaced ledges or shoulders 3| provided in the similarly shaped channel sections 3|, 32 and 33. The side sections 32 and bottom section 33 are received within the recesses or grooves 22 in the side lambs and sill of the frame. The upper channel section or meeting rail 3| is shown as detachably secured to the side sections by means of a tapping block 34 inserted at the opposite ends of this upper section and to which block these sections are attached by means of machine screws, bolts or the likeji. The bottom section and side sections are preferably secured in the recesses or grooves 22 by similar machine screws, boltsor the like and their abutting ends may be connected by welding or the like.

In order to mount the glass A firmly in the sash members each sash rail is formed with an exterior flange 36, a shoulder 31 and a slot or groove 33 which is shown as undercut in order to provide an overhanging lip 39. A stop or retaining member for the opposite side of the glass comprises a glass retaining flange 40, a

shoulder 4| with its upper or inner surface formed to provide a cam face, and a projection or lip adapted to be received beneath the overhanging lip 39 and retain the stop in its adjusted position. The rounded or cammed inner or rear surface of the shoulder 31 and the cammed upper or outer surface of the shoulder 4i provide cam surfaces to receive and direct the stop or retaining member into its locked position in the slot or groove 33. In the assembly of .the glass, each pane A is set in putty or other suitable plastic 42 as shown in Figs.. 2, 3, and '7. The stop or retaining member is then forced into the slot or groove 33 by a slight tilting or camming action and the projection or lip 39 is locked within the undercut slot and under the shoulder 3'1. Additional putty or other waterproof plastic material is then forced into the space between the flange 43 and the pane of glass, after which the sash is completely glazed.

The frame 3 is so contoured as to provide an inner trim 44 adapted to receive a screen 45 having a suitable frame 46 channelled to receive an interlocking arcuate member 41 for tensionally securing the ends of thescreen. In order to retain the upper sash 5 in its raised and intermediate lowered position, the invention comprehends spaced openings 43 in the opposed parting strips or channel members 20 adapted to receive a catch 49 of a latch member 50. As shown in Pig. 4, this latch member has a fixed hand grip 5i and a spring pressed handle or grasping portion 52 which is pivotally mounted and normally held in raised position by the pressure of the spring against a fixed abutment 53, in which position the catch 49 will seat in one of the openings-43. Preferably one of the latch members is mounted upon each side rail with this latch mechanism or hardware secured by means of an angular plate 54 and machine screws, bolts or the like to the meeting ends of the side rails 3 and top rail 1 of the upper sash. In order to limit the lowered position of the upper sash, the invention contemplates mounting a stop member 55 in the opposite side channels l'l against which a bumper 56, carried in the lower sash rail and constructed preferably of rubber or the like, will engage.

aces-toe It will be appreciated that the novel invention comprises a unitary window construction that may be completely assembled at the factory and readily mounted in a window opening, and when so mounted, provides a watertight assembly particularly well adapted for marine use.
